Has anyone here used the Marilyn Doheny 25" wedge ruler? I just bought it today & can't wait to experiment. But until I finish 2 projects i have going I'm not even going to get side tracked. Looks like it can be used for soooo many different things (all circular). I do plan on making Christmas Tree skirts with it & see how they go. I use to make Christmas Tree skirts many moons ago but not with this ruler. I can't wait to play...
